But will Andi's patch work well for you?  Adding a MODULE_INFO() tag to
every module?  I just thought since you were already using modversions
in enterprise distros already, that adding it there would be the
simplest.

If I am wrong, great, let's revert this and add something that you
really will use, otherwise it's just pointless code :)

Perhaps adding a MODULE_INFO() tag for the entire gcc and ld flags would
be nice in the end, as others have pointed out in this thread, but I
don't know if that solves your issue here or not.

thanks,
